Thanks for the hint!!!
That hack would be fast, especially if only one screen clear before the redraw. You need a slight delay before the redraw to be sure the erase is (mostly) complete before the redraw.
Alternatively, there is probably something you can poke somewhere in /sys to change the screen refresh method.
